Our nearest relatives, the primates, eat little to no meat and have very similar physiology to us. We seem to be a little bit better adapted to eat meat if necessary but our bodies are still optimized for extracting nutrients from plants.
We don't have the physiology of a carnivore at all. We look a lot more like herbivores that may have made some small adaptations to include some meat in our diets if necessary.
